Before starting with the conversion of electron volt to joule, let us first understand what these units are and when they are used. An electron volt is a unit used to describe the amount of energy gained by an electron when it is being accelerated under a potential difference of 1 volt. When an electron, at rest, is moved through a potential difference of 1V, whatever energy is gained by it is termed as 1 eV.
eV is the short form of electron-volt. It is a unit of energy. Particularly, this symbol is used in high-energy physics.
eV has many forms, such as KeV, MeV, GeV, or TeV. Also, joule is the energy of work. It is a derived form of energy. In this article, you will learn how to convert electron-volt into joule and vice versa.

Conversion of eV to Joule
Have you ever wondered about the relationship between joule and eV? Both joule and eV are units of energy. However, they are found in two different systems.
Scientists have predicted their relation in a mathematical form. Do you know, 1eV is equal to how many joules?
1 eV to J can be written as:
1eV = 1.602 × 10-19 J
In the above expression, eV = electron volt and J = joule
How Do You Explain the Unit ‘Joule’?
1 unit joule is the amount of work done or transfers of energy on an object with a force of 1 newton that acts on the object in the identical direction of its motion along 1 metre of distance.
The formula for 1 J = 6.2415 × 1018 eV
The conversion of eV to joule is very significant. The values can be used to solve multiple problems in Physics. The table given below will show the conversion values of eV to joule:
Conversion of Joules to Electron-Volt
The above table shows you the eV to joule conversion. Now, it is time to reveal the conversion of joules to eV. The table given below will show you some values which are the conversion of joules in eV:
Application of eV and Joule
electron-volt to joule conversion is also important for solving different types of problems in physics. The values given in the table are very useful for easier calculation. You need to understand the concept and memorise the conversion values for better results. Both are commonly used as units of energy.
-
The implementation of eV is everywhere, such as the atomic state, solid-state, nuclear physics and Particle physics.
-
The value of 1eV is validated again under the redefinition of SI base units in 2019. Also, eV is used with different metric prefixes, such as mega-, kilo-, giga-, tera-, peta-, and exa-.
Also, the SI unit for energy is joule. Both are different but can be related to each other. volt and electron volt are two different units. eV is symbolised for energy whereas volt is the resultant SI unit from electric potential.
